Child-Resistant Package Assembly with Sliding Inner Card
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current child-resistant packaging for medicaments is ineffective as it is difficult for adults, especially elderly patients, to access the contents while still being easily opened by small children, necessitating a packaging solution that balances child-resistance with adult usability.
Innovation Solution
A package assembly comprising an outer carton with a release mechanism and an inner product support card with flaps and a locking tail, where the support card is secured within the carton and can be partially removed by actuating the release mechanism, featuring a tamper-evident cover flap and misaligned thumb notches for enhanced security.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If child-resistant packaging is used to prevent children from accessing medicaments, then child safety is improved, but ease of operation for adults deteriorates
Solution Approach 1:
The packaging is divided into multiple functional components: an outer carton providing structural protection, an inner product support card holding the medicaments, and a tamper-evident seal. This segmentation allows each component to address specific requirements - the outer carton provides durability, the inner card enables easy product access, and the seal ensures child resistance and tamper evidence independently.
Solution Approach 2:
The inner product support card acts as an intermediary between the outer carton and the medicaments. It can be partially removed from the outer carton to provide access to the products without requiring full disassembly of the packaging, thus maintaining child resistance while enabling adult usability.
2Reliability
If secure packaging is used to prevent unauthorized access, then security is improved, but ease of operation deteriorates
Solution Approach 1:
The packaging includes pre-formed flaps and a tamper-evident seal that are prepared in advance. The flaps can be easily lifted and the seal broken to access the inner card, providing secure closure that is simple to open when needed.
Solution Approach 2:
The packaging transitions from a static sealed state to a dynamic open state through simple flap lifting and seal breaking actions. The inner card can be partially withdrawn, providing flexible access levels - users can open just enough to retrieve individual items while maintaining security for remaining contents.
3Reliability
If tamper-evident features are added to detect unauthorized opening, then security monitoring is improved, but device complexity increases
Solution Approach 1:
The tamper-evident seal utilizes visual indicators that change appearance when tampered with. The seal is designed to show clear visual evidence of attempted opening, providing simple tamper detection without requiring complex electronic or mechanical systems.
Solution Approach 2:
The tamper-evident feature is implemented as a separate seal component distinct from the main packaging structure. This modular approach allows the seal to provide tamper detection functionality independently, minimizing the complexity impact on the overall packaging system.

AI summary
Disclosed are package assemblies and methods of making the same, wherein the assemblies can include, among other elements, an outer carton defining an interior product storage compartment; an inner product support card slidably received within the product storage compartment; the inner support card having a main body portion and one or more flaps; and one or more primary product packages, each being secured to one of the one or more flaps.
